The built-in sound card does not work on this motherboard, but it works successfully from an external USB, for example, the one provided in the photo and will be included in the sales package, I think any other external sound card will work, I also think that the PCI Express sound card it will work too, but I haven't checked! That is, I did not check all PCI Express ports! The upper PCI Express works exactly!I also haven't checked all the USB connectors, although I think everything is fine there. The upper M2 works exactly, I did not check the second one. inIn the photo you can also see the disconnected radiator. This happened after I tried to tighten the bolts tightly and they broke on them. You can also see their fasteners. I think that if you really want to and have time, you can come up with something, for example, by buying a new one or using a drill. I won't say anything about the temperature regimes, since my father had it and played tanks on it for about two years) there may be overstatement, but I think it's not cretinous The memory ports are working as needed Ask questions
